Description

  In the present invention, when a parameter value is read as a value used for its own control, the parameter value corresponding to the operation of the operator is changed until the operator is once moved to a position corresponding to the read value. The present invention relates to an acoustic signal processing device having a pickup function that is not changed, and a program for causing a computer to control the acoustic signal processing device to realize such a function.

  Conventionally, in an acoustic signal processing apparatus such as an electronic musical instrument, when a parameter value is read as a value used for its own control, the operator is temporarily moved to a position corresponding to the read value. A pickup function that does not change the parameter value according to the operation is provided.

  On rotary knobs and sliders that are at the end of the operation range, the position of the operating element is associated with the value of the parameter, and the value corresponding to the position of the operating element is set as the operation of the operating element is performed. When the previously set parameter value is read, the position of the operator may not match the set parameter value. If the parameter value is changed according to the operation of the operation element in this state, the parameter value is set to a value corresponding to the position of the operation element when the operation element is operated. Will change rapidly. Such an abrupt change is not preferable because it causes unintended noise mixing into the acoustic signal.

On the other hand, if the pickup function as described above is provided, the parameter value does not change abruptly, and problems such as noise mixing can be prevented.
As an acoustic signal processing apparatus provided with such a pickup function, for example, the one described in Non-Patent Document 1 is known.

However, the conventional acoustic signal processing apparatus as described in Non-Patent Document 1 has a problem that it is difficult to know how to operate the operating element to move it to a position corresponding to the read value. If the parameter value itself is displayed, it is possible to get a rough idea by comparing the position of the operator with its value. However, the determination requires a certain amount of labor, such as converting the numerical value into the position of the operation element, and there is a problem that this point is troublesome.

Display control means to display on the display means, storage means for storing the parameter values so that they can be read later, and parameter values stored in the storage means for controlling the acoustic signal processing device. Reading means to be read as a value to be reflected, and after the reading means reads the parameter value, the value of the parameter corresponding to the operation of the operator is moved until the operation element is moved to a position corresponding to the read value. And a control means for preventing the change from being performed. When the reading means reads out the parameter value, the display means is provided with the display control means. A mark display means for displaying a mark indicating the position of the operator corresponding to the look out value, the mark when it is moved to the position indicated by the mark displayed by said mark display means the operator is operated Erasing means for erasing is provided.

Next, FIG. 2 shows a configuration of an operation panel provided in the electronic musical instrument 10.
As shown in this figure, the electronic musical instrument 10 includes an operation panel 30 including various operators and indicators. These operators form an operation unit 20, and the display unit forms a display unit 21.

  Of the operators provided on the operation panel 30, the knob 31 and the slider 32 are physical operators related to the features of this embodiment. The knob 31 can be rotated around an axis, and the slider 32 can be moved linearly in the longitudinal direction, both of which have an end in the operation range. It is also an operator used to set parameter values. However, which parameter is specifically used for setting can be selected from a plurality of choices by operating a menu or other buttons.

  The display 33 is display means for displaying various screens showing the parameter setting contents and the operation contents of the electronic musical instrument 10. This screen also includes a screen that displays the state of the controls including the knob 31 and the slider 32 and the values of parameters set by the controls.

The electronic musical instrument 10 having the above-described configuration is characterized in that the knob 31 on the display 33 when the parameter value stored in the HDD 14 is read (recalled) and stored in the current memory. And the display of the state of the slider 32 and the subsequent operation of the knob 31 and the slider 32.
Therefore, these operations will be described below.

First, FIG. 3 shows a display transition example of the knob display unit.
The knob display unit 50 is a part of a screen displayed on the display 33. And among these, the knob 51 is a part which displays the state of the knob 31. In this part, the rotation position of the knob 31 is detected by using a graphic generally imitating the appearance of the knob 31, and the knob 31 points to it. By displaying the line 51a at the same position as the position, the rotation position of the knob 31 is displayed.
The value display unit 52 is a part that displays the value of the parameter set by the knob 31, and displays the value of the parameter as a numerical value or a character.

Here, (a) shows a state immediately after the parameter values are recalled. Here, since the recalled value does not correspond to the position of the knob 31, a mark 53 is displayed at the rotational position to indicate that fact and the rotational position of the knob 51 corresponding to the recalled value. . In the value display section 52, the recalled value is displayed as it is.
(B) shows a state in which, after the recall, the user operates the knob 31 to rotate it to the position indicated by the mark 53. Then, as shown in this figure, when the knob 31 is rotated to the position indicated by the mark 53, the mark 53 is erased to indicate that.

  The electronic musical instrument 10 is provided with a pickup function so that the parameter value is not changed according to the operation of the knob 31 until the knob 31 is moved to a position corresponding to the parameter value. Therefore, even if the knob 31 is operated, the value displayed on the value display unit 52 does not change. In addition, after the knob 31 has been moved to a position corresponding to the parameter value, the parameter value is changed according to the operation of the knob 31, so that the mark 53 is deleted after that the parameter value is changed. It can be said that it shows.

  (C) shows a state in which the user further rotates the knob 31 after the state of (b). In this state, the mark 53 is not displayed, and the parameter value is changed according to the operation of the knob 31. Therefore, the value displayed on the value display unit 52 is also a value corresponding to the position of the knob 31.

Next, FIG. 4 shows a display transition example of the slider display unit.
The slider display unit 60 is also a part of the screen displayed on the display 33. Of these, the slider 61 is a part indicating the state of the slider 32. In this part, the position of the knob of the slider 32 is detected by using a graphic generally imitating the appearance of the slider 32, and the same position as that position. The position of the knob is displayed by displaying the knob 61a.
The value display unit 62 is a part that displays the parameter value set by the slider 32, and displays the parameter value as a numerical value or a character.

  (A) to (c) show the states corresponding to (a) to (c) of FIG. In the electronic musical instrument 10, the slider 32 also has the same pickup function and mark display function as those of the knob 31. In (a), in order to indicate that the recalled value does not correspond to the knob position of the slider 32 and to indicate the position of the knob corresponding to the recalled value, a mark 63 is displayed at that position. Then, when the user operates the slider 32 to move the knob to the position indicated by the mark 63, the mark 63 is deleted as shown in (b), and the parameter value is changed according to the operation of the slider 32. Become.

  Next, processing executed by the CPU 11 to realize the pickup function and mark display function described here will be described. Note that the processing described below is processing for an operator whose state is displayed on the display 33 and a parameter set by the operator for the sake of simplicity. When processing is performed for an operator and a parameter that are not displayed, processing related to display may be passed.

First, FIG. 5 shows a flowchart of parameter recall processing.
When the CPU 11 recalls the parameter value in accordance with the user's instruction or the like, the CPU 11 executes the processing shown in FIG. 5 for each recalled parameter as a processing target.
In this process, the CPU 11 first acquires the value of the parameter to be processed (S11). If the value is not a value corresponding to the current position of the operator used for setting the parameter (S12), a mark is placed at the position indicating the parameter value as shown in FIG. In addition to displaying (S13), the pickup flag F_Pick is set to NO (S14). Thereafter, the value of the parameter to be processed is displayed on the value display unit (S16), and the process is terminated. Since the position of the operation element does not change even if a recall is performed, it is unnecessary to update the display of the operation element.

If it is a value corresponding to step S12, the pickup flag F_Pick is set to YES (S15), and the process proceeds to step S16.
Here, the pickup flag F_Pick is a flag indicating whether or not to change the parameter value in accordance with the operation of the operation element, and indicates that YES is performed and NO is not performed.

  Through the above processing, the display as shown in FIG. 3A or 4A including the display of the mark can be performed. It is also possible to set whether to change the parameter value. In this process, the CPU 11 functions as a mark display unit in step S13.

Next, FIG. 6 shows a flowchart of the operator scanning process.
This process is a process which CPU11 performs regularly about each operation element which receives operation. The execution timing may be managed by a timer such as a timer.
In this process, first, the CPU 11 acquires the position information Po_Old of the operator at the previous process and the position information Po_New of the current operator (S21, S22). The former reads data stored in the RAM 13 at the time of the previous processing, and the latter is acquired from the detection circuit 15.

  If they do not match (S23), it is determined that the operator has been operated, and the parameter value update process shown in FIG. 7 is executed (S24). Thereafter, the current position information Po_New of the operating element is stored in the RAM 13 as the position information Po_Old of the operating element at the time of the previous processing, so that the position information of the operating element is updated and the process ends. If they match in step S23, it is determined that the operator has not been operated, and the position information is updated as it is in step S25, and the process ends.

FIG. 7 shows a flowchart of the parameter value update process.
In this process, first, the CPU 11 obtains the current value of the parameter set by the operator being processed (S31). If the value of the pickup flag F_Pick is YES, the parameter value is changed to a value corresponding to the position information Po_New of the current operator in order to change the parameter value according to the operation of the operator (S33). Then, the changed parameter value is displayed on the value display section (S34), and the display of the operation element is redrawn in accordance with the position information Po_New of the current operation element (S38), and the process returns to the original process.

On the other hand, if the value of the pickup flag F_Pick is NO in step S32, if the position of the operation element has reached the position corresponding to the current value of the parameter, the parameter value as shown in FIG. The mark indicating the value is erased (S36), the pickup flag F_Pick is set to YES, the operator is redrawn (S38), and the process returns to the original process. In this case, the parameter value is not changed.
On the other hand, if not reached in step S35, the operator is simply redrawn in step S38, and the process returns to the original process.

  6 and 7, the electronic musical instrument 10 responds to the function of erasing the mark when the operation element is operated and moved to the position indicated by the mark, and the operation of the operation element until then. A function that does not change the parameter value can be realized. In the processes of steps S35 and S36, the CPU 11 functions as an erasing unit.

  According to the electronic musical instrument 10 as described above, when the parameter value is recalled, a mark indicating the position of the operator corresponding to the recalled value is displayed on the screen displaying the state of the operator. For this reason, even when the pickup function is provided, the user can easily grasp which and how much the operator is operated to change the parameter value. Therefore, the operability after recall can be improved.

  In addition, since the mark is deleted when the operation element is operated and moved to the position indicated by the mark, whether or not the user can change the parameter value by operating the operation element. Can be easily grasped. Therefore, also in this respect, the operability after the recall can be improved.

Although the description of the embodiment is completed as described above, it is a matter of course that the configuration of the apparatus, the configuration of the screen, specific processing contents, and the like are not limited to those described in the above-described embodiment.
For example, in the above-described embodiment, the knob and the slider have been described as examples of the operation element. However, as long as the operation element has an end in the operation range, other operation elements can be used. The control panel may be operable in the vertical direction, or may be capable of two-dimensional or three-dimensional operation.
Further, the parameters are not limited to those used for signal processing and waveform data generation, and more generally may be used for controlling the acoustic signal processing apparatus.

The screen that displays the status of the controls is not limited to the shape of the controls, but can be a screen that can recognize the position of the controls that correspond to the values of certain parameters. For example, such a thing may be sufficient.
Further, the pickup function and the mark display function are not necessarily provided uniformly for all parameters or operators, and may be provided for only some parameters or operators.
In the above-described embodiment, the electronic musical instrument 10 has been described as an example. However, the present invention can be applied to other acoustic signal processing devices such as a digital mixer, a recorder, an effector, a synthesizer, and a sound source device. Of course.

Further, the program of the present invention is a program for causing a computer to control the acoustic signal processing device to realize the above-described functions. In addition to being stored in advance in a ROM, an HDD, etc., a CD-ROM or a flexible disk The program is recorded on a non-volatile recording medium (memory) such as a memory, and the program is read from the memory to the RAM and executed by the CPU. The same effect can be obtained even when downloaded from an external device stored in the storage means and executed.
In addition, the configurations and modifications described above can be applied in appropriate combinations within a consistent range.

As is apparent from the above description, according to the acoustic signal processing device or program of the present invention, in the acoustic signal processing device having a pickup function, the operability after reading the parameter values can be improved.
Therefore, by applying the present invention, it is possible to provide an acoustic signal processing device with good operability.
